Problems solved by technology
[0004] However, when the above charging method is adopted, due to the shared power transmission part, the charging process and the communication process are correspondingly suspended and switched according to the program of the main charging device. When the value is too low, the communication is not timely enough, and the charging parameters cannot be adjusted in time and effectively, resulting in abnormal charging.
[0005] Therefore, the traditional charging method has the problem of low charging efficiency from the powered device

The invention provides a charging method of master-slave charging equipment and the master-slave charging equipment, the master-slave charging equipment comprises master charging equipment and at least one piece of slave power receiving equipment, the slave power receiving equipment can configure a charging interruption condition according to an actual situation, and when the charging interruption condition is satisfied, charging is stopped so that the master charging equipment establishes communication with the slave power receiving equipment. After communication is established, the slave power receiving equipment can feed back the charging parameters of the slave power receiving equipment, so that the master charging equipment can carry out charging control in time according to the charging parameters fed back by the slave power receiving equipment, passive power receiving is converted into active feedback power receiving by the slave power receiving equipment, and the charging efficiency of the slave power receiving equipment is improved.
Description
technical field [0001] The invention belongs to the technical field of charging, and in particular relates to a charging method for a master-slave charging device and the master-slave charging device. Background technique [0002] The traditional master-slave charging device charges the slave receiving device through the master charging device. In order to improve charging efficiency and safety, the master charging device communicates with the slave receiving device at a set time period or according to a preset program. Adjust the charging parameters according to the charging state of the electric equipment, so as to output the charging power required by the electric equipment. [0003] When charging, in order to reduce the signal line, the master-slave charging equipment usually shares the power transmission parts between the master-slave charging devices. The power transmission parts can be power lines, metal contacts, etc., that is, when charging, the charging power is ou...
